           —CH 2 O(CH 2 CH 2 O) n     11   H  (I-a)  
         
       
        wherein n 11  represents an integer of from 1 to 3;  
       
         
           —(CH 2 CH 2 O) n     12   H  (I-b)  
         
       
        wherein n 12  represents an integer of from 2 to 4.  
     
     
       2. The liquid processing composition for a color development of a silver halide color photographic material as claimed in  claim 1 , wherein in formula (I), at least one of R 15  and R 16  includes a hydroxyl group. 
     
     
       3. The liquid processing composition or a color development of a silver halide color photographic material as claimed in  claim 1 , wherein in formula (I), R 11 , R 12 , R 13  and R 14  each independently represents a hydrogen atom or a methyl group, R 15  is a group represented by formula 2), 5) or 11) below, or a group represented by formula (I-a) wherein n 11  is 1, R 16  is a group represented by formula 17), 20) or 26) below, or a group represented by formula (I-b) wherein n 12  is 2, M 1  is Na or K:                    
     
     
       4. The liquid processing composition for a color development of a silver halide color photographic material as claimed in  claim 1 , wherein the at least one glycol is selected from the group consisting of diethylene glycol and triethylene glycol. 
     
     
       5. The liquid processing composition for a color development of a silver halide color photographic material as claimed in  claim 1 , which.comprises the compound represented by the formula (I) in an amount of from 1 to 50 g/liter of the amount of the composition. 
     
     
       6. The liquid processing composition for a color development of a silver halide color photographic material as claimed in  claim 1 , which comprises the glycol in an amount of from 5 to 100 g/liter of the amount of the composition.
